Abstract: In this paper, we study Ricci solitons on hypersurfaces of Lorentz space E1n+1 by taking the potential vector field as the tangent component of the position vector of the hypersurfaces. Under the assumption that the hypersurfaces have diagonalizable shape operators, we prove that the hypersurfaces have at most two distinct principal curvatures.
